One real session, no cost and no obligation — in your nearest centre or online. Your child is assessed at the end of it, so you leave knowing which level they would start at.
Five is the earliest. Children of five and six begin in the Foundation module, which is slower and more physical. From seven upward they start Level 1 directly. The placement assessment at the demo decides it, not the age on paper.
Ten levels at roughly three months each — about two and a half to three years with normal attendance.
Same curriculum, same assessments, same ten-to-one ratio. The physical abacus is couriered to you. Children under seven usually do better in the centre for the first two levels.
Fees are charged per level and vary slightly by city. You receive the full fee schedule in writing at the demo, with no registration charge before that.
Ten minutes a day, five days a week. It matters more than the class itself. The portal tracks it so you can see the streak without asking.
